Yoo Seung Ho what a great performance in the role of the Crown Prince! I love Yoo Seung Ho in "I'm Not a Robot" so I knew he was going to be extraordinaire in this drama. I didn't check to see if he has a singing voice but I will. I love the visual effects and the era... I still can't get over the long ankle flared-out dresses and the high waist blouses! I guess it's better than what the roman empire women wore with their white hair bouffants and a fake booty pack. The costumes were good. Kim So Hyun is a phenomenal young actress, I love seeing her in these dramas. Then there is "L", still can't get over ONE initial for a stage name. Well, Prince had his logo for a name... so why not? I do love "Infinite's" music. The writers wrote a good drama I must say. There was no competition between female and male characters which is a plus for me. Romance Chemistry was mostly there but not all the way there. Loved the bodyguards. The supporting cast was plenty and well done! Thank you everyone at Team "The Emperor: Owner of the Mask (2017)"
